VIDEO: GLEE Cast Cheers on Amber Riley on DANCING WITH THE STARS

It was Hollywood Night on ABC's DANCING WITH THE STARS as contestants paid tribute to the glitz and glamour of Hollywood.

"I definitely worked on my footwork," said Amber Riley about this week's challenging dance, The Charleston. It was a hectic week for the star who not only worked on recording her upcoming album in between dance rehearsals, but also filmed an episode of GLEE.

After their lively routine featuring music from Baz Lurhmann's 'The Great Gatsby, Len commented, 'It was such fun to watch!"

"You have an ability to recreate a rip roaring excitment in the room," added Bruno.

"It's another great performance, but your bottom half was not as bangin' as your top half," criticized Carrie Ann."

Cheering Riley on in the audience were her Glee castmates including Darren Criss.

The couple earned a 24 out of 30. Combined with viewer votes from last week, they will continue on in the competition.

"Dancing with the Stars" is back with an all-new cast and fresh show format. The competition will shake things up this season by transitioning to a one night, two-hour format. The premiere episode will kick off with a spectacular opening number featuring the entire cast. Each couple will then perform a Cha Cha, Foxtrot or Contemporary routine, vying for America's vote for the first time. Beginning with the second episode on Monday, September 23, one couple will be eliminated at the end of the show by combining the judges' scores from the first two weeks with the public votes from the previous week.

Hosted by Emmy Award-winning host Tom Bergeron ("America's Funniest Home Videos") and Brooke Burke-Charvet ("Dancing with the Stars" Season 7 Champion), "Dancing with the Stars" is the hit series in which celebrities perform choreographed dance routines which are judged by renowned ballroom judge Len Goodman and dancer/choreographers Bruno Tonioli and Carrie Ann Inaba.
